Cold Email Outreach
You are running a cold email outreach campaign. Your job is to source qualified leads,
send a targeted email sequence, and handle replies systematically โ without paid APIs
or monthly subscriptions.
This skill covers the full methodology. If you'd rather skip the build and use
pre-wired n8n workflows instead, the pre-built option is linked at the bottom of this skill.
Before You Start
You need four things before sending a single email:
- A defined ICP โ who you're targeting (role, company size, industry, geography)
- A lead list โ at minimum 50 verified contacts in a spreadsheet
- A sending account โ Gmail or any SMTP-capable email, warmed up for 2 weeks
- A tracking system โ a Google Sheet with: Lead, Email, Company, Status, Last Contacted, Reply Category
If any of these are missing, complete them first. Sending without them wastes your list.
Phase 1: Define Your ICP
The most common outreach failure: spraying a generic message to a mixed audience.
Build your ICP by answering:
- What role feels the pain your offer solves? (Job title, seniority level)
- What company stage/size is most likely to buy? (1-10 employees? 50-200? Series A?)
- What industry or vertical is your proof strongest in?
- What signals indicate they're ready now? (Hiring, funding, tool change, new product launch)
Document your ICP as a 3-line filter:
Target: [Role] at [Company Size] [Industry] companies, showing [signal if applicable]
Example: Head of Sales at 10โ50 person B2B SaaS startups, recently hiring SDRs
One ICP per campaign. If you're targeting two different personas, run two separate campaigns.
See references/lead-sourcing.md for ICP refinement tactics.
Phase 2: Source Leads
Free sources (no credit card required)
| Source | What you get | Free limit |
|---|
| Apollo.io | Email + company data | 75 verified leads/month |
| Hunter.io | Domain email finder | 25 searches/month |
| LinkedIn (manual) | Profile data, job titles | Unlimited (manual work) |
| LinkedIn CSV export | Sales Navigator export | Requires Sales Nav trial |
| Google Sheets (hand-built) | Any list you build | Unlimited |
Lead sourcing workflow
- Build your filter in Apollo โ role, company size, industry, location. Export as CSV (up to 75/month free).
- Verify emails โ Apollo provides verified emails. For other sources, run through Hunter.io's email verifier before importing.
- Deduplicate โ remove any email addresses you've contacted in the last 90 days.
- Clean the list โ remove:
- info@, hello@, contact@ (catch-all mailboxes, low deliverability)
- Role-based addresses (support@, sales@) unless that's your target
- Any domain on your suppression list
- Import to tracking sheet โ columns: First Name, Last Name, Email, Company, Title, Source, Status (set to "new"), Notes
Volume guidance
- Ideal batch size: 20โ40 new leads per week for a solo sender
- More than 50/day risks deliverability flags on Gmail free tier
- Quality > quantity: a 200-lead list of perfect-ICP contacts outperforms a 2,000-lead spray
See references/lead-sourcing.md for advanced sourcing tactics.
Phase 3: Write the Email Sequence
Sequence structure: 3 touches over 7 days
| Touch | Timing | Purpose | Length |
|---|
| Email 1 | Day 0 | Lead with value, one soft ask | 5โ7 sentences |
| Email 2 | Day 3 | Different angle or proof point | 3โ5 sentences |
| Email 3 | Day 7 | Final touch, close the loop | 2โ3 sentences |
Writing principles
Write like a peer, not a vendor. Each email should read like it came from a smart colleague who noticed something relevant โ not a sales machine following a script.
Lead with their world, not yours. The reader should see their own situation reflected back. "You/your" should dominate over "I/we."
One ask, low friction. Interest-based CTAs ("Worth 15 minutes?" / "Relevant to what you're working on?") consistently outperform meeting requests.
Subject lines: short, boring, internal-looking. 2โ4 words, lowercase. Looks like an internal forward, not a marketing blast.
Email 1 โ Observation + Problem + Proof + Ask
Subject: [2โ4 word lowercase line]
[Personalized observation about their company/role/situation]
[Bridge to the problem you solve โ connect the observation to the pain]
[One sentence: what you do + proof point or result]
[Soft CTA: "Worth a quick look?" or "Relevant?"]
[Name]
Email 2 โ Different angle or proof
Subject: [re: or new 2โ4 word line]
[Acknowledge you're following up โ one phrase, not a paragraph]
[New angle: a different pain point, a specific result, or a case study]
[CTA: same or slightly more specific โ "15 minutes this week?"]
[Name]
Email 3 โ Clean close
Subject: [re: same thread or "last note"]
[Last touch โ close the loop, leave the door open]
Example: "Last email on this โ didn't want to leave it hanging. If timing's off, happy
to reconnect later. Just reply 'later' and I'll reach back out in 90 days."
[Name]
Personalization: the 3-minute system
For every email, identify one specific signal about this person before writing:
- Recent LinkedIn post โ "Your post on X caught my eye"
- Job posting on their site โ "Noticed you're hiring SDRs โ outbound scaling?"
- Company funding โ "Congrats on the raise โ growth stage usually creates X challenge"
- Tech stack โ "I see you're on HubSpot โ most teams at your stage hit a ceiling with X"
The personalization must logically connect to the problem you solve. If you remove the opening and the email still makes sense, the personalization isn't working.
See references/email-sequences.md for full templates + subject line data.
Phase 4: Send the Sequence
Gmail / SMTP setup
- Use a separate sending account, not your primary inbox
- Warm the account for 2 weeks before sending cold: send 5โ10 real emails/day to friends, colleagues, lists you're subscribed to. Get replies if possible.
- After warming: start at 10โ20 emails/day, increase by 10/day over 2 weeks to a max of 50/day on Gmail free tier
Scheduling
- Send emails TuesdayโThursday, 9โ11 AM (recipient's timezone if known, yours if not)
- Space batch sends: don't send 40 emails at 9:00:01 AM โ stagger by 2โ5 minutes each
Manual tracking (no automation)
Update your tracking sheet after each send:
- Status โ "emailed-d0"
- Update to "emailed-d3" after touch 2, "emailed-d7" after touch 3
- Log any out-of-office replies immediately (status โ "ooo", note return date)
With n8n automation
If you're running this via n8n:
- Workflow 2 (Email Sequencer) reads your Google Sheet, sends on schedule, logs status back
- Runs daily at 9 AM โ only sends to rows where Status = "new" or queued for next touch
- See references/tools-free-tier.md for n8n setup
Phase 5: Handle Replies
Reply categories
Every reply falls into one of five buckets. Handle each the same way every time:
| Category | Signal | Action |
|---|
| Interested | "Tell me more," "let's chat," "send me info" | Move to "hot" tab, respond within 1 hour, book the call |
| Not now | "Reach out in Q3," "timing isn't right" | Log the timeframe, set a reminder, reply with a graceful close and re-contact date |
| Not interested | "No thanks," "not relevant," "don't contact me" | Status โ "unsubscribed," add to suppression list, do not follow up |
| Objection | "We already use X," "too expensive," "how is this different" | Respond with one specific answer to their objection, re-ask the CTA |
| OOO | Out of office auto-reply | Note return date, reschedule touch to day after return |
The hot lead response (within 1 hour)
Subject: re: [same thread]
Great โ I'll keep it short.
[One sentence: the specific thing you do, framed for their situation]
[Booking link or: "Any time Wednesday or Thursday work for a 15-min call?"]
[Name]
Suppression list management
Maintain one suppression sheet (tab or separate file):
- Every unsubscribe request goes here immediately
- Before importing any new batch, cross-reference against suppression list
- Never re-contact a suppressed email โ even if they show up in a new Apollo export
See references/reply-handling.md for full response playbooks.
Phase 6: Measure and Iterate
Metrics that matter (per 100 emails sent)
| Metric | Benchmark | If Below Benchmark |
|---|
| Open rate | 30โ50% | Subject lines weak โ test new ones |
| Reply rate | 5โ15% | Copy weak or ICP off โ rewrite Email 1 |
| Positive reply rate | 1โ5% | Offer not resonating โ check ICP or value prop |
| Unsubscribe rate | <3% | If above: message is spam-feeling or ICP wrong |
Iteration cycle
After every 50 emails sent, review:
- Which subject lines had highest opens?
- Which emails got replies (positive or otherwise)?
- Which ICP segment responded most?
Change one variable at a time. Don't rewrite the whole sequence โ you'll lose the signal.

Quick Reference
Phase sequence: ICP โ Source โ Write โ Warm โ Send โ Handle โ Measure
Weekly rhythm (solo sender, no automation):
- Monday: source 20 new leads, clean list, import to sheet
- TuesdayโThursday: send 10โ15 emails/day (new + follow-ups)
- Friday: check replies, update statuses, plan next week
Red flags to fix immediately:
- Open rate drops suddenly โ check if emails are landing in spam (send a test to yourself)
- Reply rate drops โ your ICP shifted or the market is saturated for your offer
- Bounce rate above 5% โ your email verification is broken, pause and re-verify the list
